Hi PCI/ACPI PM experts,

Since Linux 4.8, nouveau switched to rely on the PCIe port driver to
transition to D3cold. This however does not happen for an Acer Aspire
V7-582PG (Haswell, NVIDIA GTX 750M) from Rick.

Any idea why? acpidump, lspci, dmesg and other details can be found in
the linked bug below.

Kind regards,
Peter

The ASL code looks right to me (except for the NVP2 which never set _STA
to 0 but should not affect here).

I wonder what does /sys/bus/pci/devices/0000:00:1c.4/firmware_node/path contain?

The value is as expected, \_SB.PCI0.RP05:

/sys/bus/pci/devices/0000:00:1c.4/firmware_node/path:\_SB_.PCI0.RP05
/sys/bus/pci/devices/0000:00:1c.4/firmware_node/power_state:D3hot

And there are no power_resources_Dx directories under
/sys/bus/pci/devices/0000:00:1c.4/firmware_node?

You need to build the whole kernel, install and reboot.

So Rick has tested this patch now on top of 4.8.4 (mainline fails to
boot due to a kbuild issue which I reported elsewhere), but the output
is empty. That seems to indicate that flags.power_resources is unset.

Given that _PS3 exists and is indeed a package with some elements, it
seems that acpi_extract_power_resources is failing. Note that in the
SSDT, the power resource NVP3 was referenced before it was defined,
could that result in this enumeration failure? Relevant SSDT excerpt:

    Scope (\_SB.PCI0.RP05)
    {
        Name (_PR3, Package (0x01)  // _PR3: Power Resources for D3hot
        {
            NVP3
        })
        // ...
    }

    PowerResource (NVP3, 0x00, 0x0000)

Kind regards,
Peter

Is it completely empty or is it empty just for RP05? It should print out
all devices with power resources.

That and the fact that they come from an SSDT instead of DSDT may cause
this. However, I'm not expert in ACPICA so adding Bob and Lv if they
have ideas.

Bob, Lv, the bug in question is: https://bugs.freedesktop.org/show_bug.cgi?id=98398

\NVP2 and \NVP3 are the only power resources under RP05 and defined in
SSDT1, there are no others.

We should probably add a debug print before checking
flags.power_resources just to be sure the patch is correctly applied.

It was correctly applied. I did some testing with QEMU, it seems that
the \_OSI check is problematic. Removing it makes things work again.

To reproduce:

 1. Build the kernel with the attached config (minconfig with ACPI and
    printk stuff enabled) and debug patch.
 2. Compile the attached ASL file to AML (iasl ssdt1.dsl).
    (You can remove the If(\_OSI(...)) check to see the difference.
 3. Boot QEMU and watch the dmesg for the debug prints.

Alternatively, just boot QEMU with this SSDT and check against any Linux
distro and inspect /sys/bus/pci/devices/0000:00:01.3/firmware_node/.

Tested with Linux v4.8.5, QEMU 2.7.0, iasl 20160831. The SSDT structure
is adapted from Ricks SSDT1 file and modified for the 00:01.3 device in
QEMU. The QEMU command I used was:

    qemu-system-x86_64 -m 1G -M pc,accel=kvm -nographic \
        -kernel arch/x86/boot/bzImage -serial file:/dev/stdout \
        -acpitable file=ssdt1.aml \
        -append 'console=ttyS0 acpi.aml_debug_output=1'

I hope Bob and Lv can answer why _OSI fails.

In the meantime I think we should check flags.power_resources in nouveau
driver (in addition to _PR3) so that it falls back to _DSM if there are
no power resources (or if we failed to evaluate them for some reason).

IMO, the problem wasn't _OSI, the problem was "If".
"If" is module level here.
So execution order of it in current Linux upstream may be different from Windows.

You can try to modify acpi_gbl_parse_table_as_term_list to TRUE.
To see if this can be solved.

Thanks and best regards
Lv

It seems that acpi_gbl_parse_table_as_term_list is a new flag in
v4.9-rc1. Changing the flag to TRUE in in include/acpi/acpixf.h has no
effect other than:

    ACPI: Executed 2 blocks of module-level executable AML code

changing into:


    ACPI: 2 ACPI AML tables successfully acquired and loaded

That was tested using v4.9-rc2-40-g9fe68ca + debug patch from previous
mail, but with a slightly modified QEMU command (to allow the device to
become visible in Windows Device Manager) and slightly modified SSDT1:

    qemu-system-x86_64 -M pc,accel=kvm -m 2G -acpitable file=ssdt1.aml \
        -net none -device pci-bridge,addr=12.0,chassis_nr=2,id=head.2 \
        -device isa-debugcon,iobase=0x402,chardev=dbug \
        -chardev file,id=dbug,path=/dev/stdout ...

With this command and Windows 10 (-drive file=w10.qcow2), I can see that
the power resource methods are invoked (stdout | grep PR_TEST):

    PR_TEST: NVP3._ON
    PR_TEST: NVP2._OFF
    PR_TEST: _PS0
    PR_TEST: _S0W
    PR_TEST: NVP3._ON
    PR_TEST: _PS0

Using the above test setup with Linux (-kernel arch/x86/boot/bzImage):

    PR_TEST: _S0W

If you think that the default runtime PM state affects this, note that
the dmesg also shows:

    ACPI: \_SB_.PCI0.S90_: Adding power resources for device:14? 0

Looks wrong order to me.

However, _PR3 is a package, for AML opcode that contains PkgLength grammar primitive, forward reference may be OK (for example Method).
DefPackage := PackageOp PkgLength NumElements PackageElementList
DefMethod := MethodOp PkgLength NameString MethodFlags TermList
As when it is encountered, AML interpreter may only saves entire packaged object.

I need to test behaviors around Package with qemu but I don't have environment now.
Can you help to give it a try?
By adding customize an ssdt with the above code putting under root scope,
DefinitionBlock ("ssdt-package.aml", "SSDT", 2, "INTEL ", "PACKAGE ", 0x00003000)
{
    Scope (\)
    {
        Name (_PR3, Package (0x01) { NVP3 })
    }
    PowerResource (NVP3, 0x00, 0x0000) {}
}
Running Windows images on qemu with this ssdt appended "-acpitable file=ssdt-package.aml".
To see if blue screen can be resulted.

Thanks

Testing this code with Windows 10 gives a BSOD, changing the order of
the PowerResource and Scope does not make a difference. If I take my
previous SSDT and change the ordering of NVP3 definition vs _PR3 use,
there is no change.
